[Correspondence] Preventing childhood obesity starts during pregnancy
Tim Lobstein and colleagues (June 20, p 2510)1 highlight the global childhood obesity epidemic and the need for preventive strategies. However, greater emphasis on prevention before birth is needed. We have shown that similar fetal growth is observed in mothers at low risk of nutritional, social, and medical constraints,2 which justifies using the newly published international newborn standards3 that complement the existing WHO Child Growth Standards. These standards describe how individuals should grow, by contrast with the many current references describing how they have grown at a particular time or place.
